Diving into Secure Access Service Edge

By: Jeremiah

Overview of this book

The SASE concept was coined by Gartner after seeing a pattern emerge in cloud and SD-WAN projects where full security integration was needed. The market behavior lately has sparked something like a "space race" for all technology manufacturers and cloud service providers to offer a "SASE" solution. The current training available in the market is minimal and manufacturer-oriented, with new services being released every few weeks. Professional architects and engineers trying to implement SASE need to take a manufacturer-neutral approach. This guide provides a foundation for understanding SASE, but it also has a lasting impact because it not only addresses the problems that existed at the time of publication, but also provides a continual learning approach to successfully lead in a market that evolves every few weeks. Technology teams need a tool that provides a model to keep up with new information as it becomes available and stay ahead of market hype. With this book, you’ll learn about crucial models for SASE success in designing, building, deploying, and supporting operations to ensure the most positive user experience (UX). In addition to SASE, you’ll gain insight into SD-WAN design, DevOps, zero trust, and next-generation technical education methods.

SASE Policy

SASE Policy defines every high-level function in SASE and most of its lower-level functions. It defines security in every sense of the word, as well as quality, performance, data flow, packet forwarding, traffic shaping, who, what, when, why, where, and how much for everything. With SASE, access to the network, access to the applications, and even access to devices are controlled with a policy. If a SASE Session is the heart of SASE, then SASE Policy may be identified as the lungs that breathe life into a SASE Service.

In this chapter, we will cover SASE Policy and discuss quality mechanisms, dynamic policy mechanisms, how trust is leveraged, and how to design an effective policy. SASE Policy can deliver exceptional quality and performance, or it can deliver more damage than anything else in the SASE framework.

In this chapter, we will cover the following topics:

  • SASE Policy – explain what SASE Policy is and how it is different
  • SASE Quality –...
